CONCRETE BUILDING AND HOLDING MECHANISIVI.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed March 28, 1908. Serial No. 423,895.

To all whom it may concern:

Be it known that I, ARTHUR NATHAN DoUD, a citizen of the United States, residing at North Stockholm, in the county of St. Lawrence and State of New York, have invented a new and useful Concrete Building and Holding Mechanism, of which the following is a specification.

The primary object of the present invention is to provide a holder or receptacle, together with novel and effective means whereby concrete or other material placed in said holder or receptacle can be delivered from the same in any amount desired, thus making the structure particularly useful in connection with the construction of concrete buildings, floors, walls, and the like, the holder or receptacle being transported.

One embodiment of the invention is illustrated in the accompanying drawings, but it will be evident from an inspection of the appended claims that said invention is not limited to the structure disclosed.

In the drawings: Figure 1 is a side elevation of the mechanism. Fig. 2 is a vertical sectional view therethrough. Fig. 3 is a vertical sectional view at right angles to Fig. 2. Fig. 4 is a top plan view of the spreader. Fig. 5 is a side elevation of the lower' portion of a modification of the invention. Fig. 6 is a detail sectional view on the line 6 6 of Fig. 5.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a base is employed, comprising spaced sections 9, from which rise standards 10. These standards are preferably channel bars, and secured to their upper ends, is a holder or receptacle in the form of a hopper 11. The upper ends of the standards are outturned so as to rest against the opposite side walls of the hopper, and are secured thereto by bolts or rivets 12 and angle brackets 13, which are fastened to the standards and to the adjacent walls. It will be noted that these standards are located at one side of the vertical center of the hopper.

A pivot bolt 14 connects the base sections 9 and bridges the space between them, thereby constituting a tie between said sections. This pivot bolt, as shown more particularly in Figs. 2 and 3, is located at one side of the center of the hopper. The bottom of said hopper is open, but a closure is provided therefor, and is in the form of a plate 15, which is curved concentrically to the axis of the pivot 14 and has depending side ears 1G secured thereto and journaled on the pivot. The ears 16 are preferably connected to the plate 15 by angle irons 17, and extend upwardly above the lower edges of the hopper, outside the same, forming guide flanges, as illustrated in Fig. 3. g

The location of the standards 10 at one side of a plane transversely cutting the vertical center of the hopper and the location of the pivot bolt for the closure passing through the standards as shown in Fig. 3 are important. The pivot bolt acts as a brace for the lower ends of the standards and also performs its proper function as the pivot for the closure. It is preferable that the pivotal axis of the closure or gate should be to one side of a vert-ical plane transversely cutting the center of the hopper, for the reason that in this position the gate or closure will remain in position when closed by the action of gravity; that is, when the gate is closed, the natural tendency of the gate is to remain closed because of its being pivoted to one side and this without the necessity of using any latch for the purpose of holding the gate closed. The standards reinforce the pivotal engagement of the gate. Therefore, the pivot bolt passes through the standards, and in order to provide for gravity holding the gate closed, the standards and the pivot bolt are mounted to one side of the center. It will thus be seen that these parts and their location have a special value in this construction. While any suitable means may be employed for operating this closure, in the present embodiment, a yoke is provided that embraces the hopper and comprises a cross bar 18 and side arms 19, the latter forming levers that are fulcrumed as shown at 20 between their ends on the opposite sides of the hopper. The upper and inner ends of the arms 19 are pivoted as shown at 21 to links 22, and the lower ends of said links are pivotally connected as illustrated at 23 to the opposite sides of the closure. Stops 24 limit the swinging' movement of the arms, and said arms and consequently the yoke are normally held against movement by a latch 25 pivotedl on thehoppery and engaging a pin 26 carried by one of the arms 19; It will thus be evident that by swinging the yoke, the closure may be-opened to any extentdesired.

Weans for spreading or directing the inaterial from the hoppei' is also employed. In the embodiment shown, this means consists of an inverted substantially V-shaped structure constituting' a spreader Q7, the opposite divergent walls 28 of which are suitably braced, as shown at 29. This spreader has depending earsSO that are mounted on thepivot 14., anda holding bar comprising angularly. disposed, arms 31 and 82 is empl'oyed for maintaining the spreader against movement,` the arm 31. being fastened as showny at` 33. to the side ofthe hopper; the arm SQ-being connected to the walls of the spreader. Sleeves 30a are located. between the various ears and between the outermost ears and base.

The operation of the structure will be clearly evident. If the yoke 18-19 is unlatched, it will be evident that by swinging the same, the closure may, be opened to any extent desired, and the material, gravitating from the hopper, will be spread or divided by the device located beneath the same and onlwhich it falls. This holder may be employed inv various ways. For instance, it may be placed upon a car, or it may be suspended' from a derrick or other suitable structure. For the latter purpose, ears Bil are connected to its upperv end.

In case no spreading means is employed and the material. is to be` delivered downwardly, the structure disclosed in Fig, 5 is preferably utilized. In this embodiment of the invention, the base is designated 85, and the hopperl 86'is mounted on thestandards, one of which is shown at 37. The pivot in the present embodiment comprises two short stubs, one of which is illustrated and designatedSTa.' This stub has its outer end engaged in one of the base sections and is also embraced by a reinforcing strap 38. The inner end of th'e stub-pivot has mounted thereon an ear 39 of theswinging closure 40. Inother words, this form of'construction is substantially the same as that first shown, except that the pivot is made in two sections, andthe particular advantage for this arrangementV is that there is nothing in the nature of an obstruction beneath the receptacle or hopper that will interfere with the passage of concrete or materiaL From the foregoing, itis thought that the construction, operation and many advantagesof the herein describedinvention will be apparent to those skilled in the art, without further description, and it will be understoodthatvariousfchanges in the size, shape, proportiomand minor details ofconstruction, may be resorted'to without departing from. the spirit or sacrificing any of the advantages ofV the invention.

Having thus fully described my invention,
